阅读 A｜Saving Information That Needs to Survive

When an application saves information, I need to know what has been saved, where it is stored, and how long it is expected to remain.

A visible confirmation can show that one request succeeded, but it does not explain what will happen after a restart or a migration.

Some data belongs in the database, while temporary interface state may exist only in the current browser session or running process.

For a learning product, completed lessons and saved vocabulary usually need to remain available when the learner returns on another day.

The position of an open dialog may not require the same treatment, depending on the experience that the product intends to offer.

I ask for these choices to be explicit so that a local convenience does not accidentally become the only copy of important information.

Before changing storage behavior, we review the existing records and identify which values are shared, private, temporary, or safe to regenerate.

We also check whether the new version can read information that was saved by the old version before the change.

A successful update should preserve the data that the user expects to keep, rather than merely make the newest empty example work.

Understanding persistence helps us describe the real behavior of the product and plan changes without making unsupported promises about what survives.

A：逐句中文对照

When an application saves information, I need to know what has been saved, where it is stored, and how long it is expected to remain. 应用保存信息时，我需知道保存了什么、在哪里，以及应保留多久。

A visible confirmation can show that one request succeeded, but it does not explain what will happen after a restart or a migration. 可见确认能显示请求成功，却不解释重启或迁移后怎样。

Some data belongs in the database, while temporary interface state may exist only in the current browser session or running process. 部分数据属于数据库，临时界面状态可能只在当前浏览器会话或进程中。

For a learning product, completed lessons and saved vocabulary usually need to remain available when the learner returns on another day. 学习产品中，已完成课程和生词通常需次日仍可用。

The position of an open dialog may not require the same treatment, depending on the experience that the product intends to offer. 打开对话框的位置则未必同样处理，取决于产品体验目标。

I ask for these choices to be explicit so that a local convenience does not accidentally become the only copy of important information. 我要求明确这些选择，避免临时本地方便方案意外成为重要信息唯一副本。

Before changing storage behavior, we review the existing records and identify which values are shared, private, temporary, or safe to regenerate. 改存储行为前，检查现有记录，区分共享、私人、临时或可重建值。

We also check whether the new version can read information that was saved by the old version before the change. 也检查新版能否读取改动前旧版保存的信息。

A successful update should preserve the data that the user expects to keep, rather than merely make the newest empty example work. 成功更新应保留用户预期保留的数据，不只是让全新空例子可用。

Understanding persistence helps us describe the real behavior of the product and plan changes without making unsupported promises about what survives. 理解持久化有助于描述真实行为，规划改动而不无依据承诺数据保留。

阅读 B｜Planning a Backup and a Restore

A backup is useful only if we understand what it contains and how the information can be restored when it is needed.

Before a database migration, I ask for a current export and record which environment, date, and application version it belongs to.

The file should be stored in an appropriate location with access that matches the sensitivity of the information inside it.

I also want to know whether the backup includes only database records or the uploaded files that those records refer to.

A record with an image path is not the same thing as the image itself, so these two resources may need separate handling.

The restore procedure should explain the required starting state and the effect it will have on information that already exists.

If the procedure replaces current data, that consequence needs to be understood before anyone uses it in a live environment.

We can then plan a suitable check that shows whether the restored application can actually read its records and associated files.

I keep the explanation connected to the actual project, because a generic instruction may omit a service or resource that this application requires.

A documented backup and restore process gives the team a clearer understanding of what has been protected and what still depends on another system.

B：逐句中文对照

A backup is useful only if we understand what it contains and how the information can be restored when it is needed. 备份只有在知道内容及需要时如何恢复，才有用。

Before a database migration, I ask for a current export and record which environment, date, and application version it belongs to. 数据库迁移前，我要求当前导出，并记录所属环境、日期和应用版本。

The file should be stored in an appropriate location with access that matches the sensitivity of the information inside it. 文件应放在合适位置，访问权限需符合内部信息敏感性。

I also want to know whether the backup includes only database records or the uploaded files that those records refer to. 我也想知道备份只含数据库记录，还是包含记录所指上传文件。

A record with an image path is not the same thing as the image itself, so these two resources may need separate handling. 图片路径记录不等于图片本身，因此可能需分别处理。

The restore procedure should explain the required starting state and the effect it will have on information that already exists. 恢复流程应解释起始条件，以及对既有信息产生的影响。

If the procedure replaces current data, that consequence needs to be understood before anyone uses it in a live environment. 若流程替换当前数据，在真实环境执行前必须理解后果。

We can then plan a suitable check that shows whether the restored application can actually read its records and associated files. 之后安排适当核对，确认恢复后的应用确实能读记录和关联文件。

I keep the explanation connected to the actual project, because a generic instruction may omit a service or resource that this application requires. 我把说明与实际项目连接，因为通用指令可能遗漏本应用依赖服务或资源。

A documented backup and restore process gives the team a clearer understanding of what has been protected and what still depends on another system. 有文档的备份恢复流程让团队明确保护了什么，以及哪些仍依赖其他系统。

工作对话

Me: Before changing the database structure, could you export the current data and explain exactly which files and records the backup will contain? 我：改数据库结构前，能导出当前数据并说明备份含哪些文件记录吗？

Developer: The database export will contain the records, but uploaded images are stored separately, so their files require a separate backup or reference. 开发者：数据库导出含记录，上传图片另存，需要单独备份或引用。

Me: Please record the source environment and date, and keep the backup in a location appropriate for the private information that it contains. 我：请记录来源环境日期，并按私人信息要求放在合适位置。

Developer: I will also describe the restore procedure, including which services must be available and whether restoring will replace any existing records. 开发者：还会说明恢复流程，包括所需服务与是否替换既有记录。

Me: Have the learner progress and saved vocabulary been included, or does the export cover only the public course content that visitors can read? 我：包含学习进度和生词了吗，还是只有访客可读的公开课文？

Developer: Both are included in this export; I will list the relevant tables so that the scope is explicit rather than assumed. 开发者：此次两者都包含，我会列相关表，明确范围。

Me: Good; after the migration, check whether the application can still read the old records and open the files associated with them. 我：好，迁移后检查应用是否仍能读旧记录并打开关联文件。

Developer: I will report which data has been preserved and identify any resource that remains outside the backup or depends on a separate system. 开发者：会报告保留数据，并标明备份外或依赖独立系统的资源。

语法精讲与结构拆解

G15-1 现在完成时

We have saved the learner’s progress.

have＋过去分词，强调截至现在的完成及结果。过去明确时间用一般过去时，如saved yesterday。

对照／迁移：Have you exported the records yet?

G15-2 完成时被动

Have the records been included?

have＋主语＋been＋过去分词；主语records被包含。疑问句have置前。

对照／迁移：The files have been backed up.

G15-3 主谓一致与不可数

The information is stored separately.

information不可数，谓语单数；records复数用are。data在普通技术语境可作整体或复数，全文应一致。

对照／迁移：Each record has a path. / The records have paths.

相关结构补充与易错点

现在完成时：have/has＋过去分词

用于说明截至现在已完成的动作，常用 already、yet。

• Have you pushed the changes yet? 你已经推送改动了吗？
• I’ve already updated the page. 我已经更新页面了。

完成时被动：has/have been＋过去分词

用于问部署、上传、保存等动作是否已完成。

• Has the update been deployed? 更新已经部署了吗？
• Have the files been uploaded? 文件已经上传了吗？
